Mumbai Joint Commissioner of Police, Crime, Meera Borwankar, who had been keeping a low profile since taking charge mid last year, on Monday warned that strict action would be taken against imposters extorting money using the department's name.

"We are working hard to detect the cases, and if somebody is found extorting money using our name, we will take tough action," said Meera, the first ever woman to head Mumbai's crack crime branch unit.
